It wasn't bad at all, in fact the doc gave him something to calm him down before and he was quite silly and jovial during the whole thing. (my dh, not the doc. ) The pain wasn't bad at all. He said the most uncomfortable part was the sensation of the stitches inside until they dissolved and the tugging feeling from where the doc had pulled at the tubes to cut them. It felt weird to him for about a month. ETA: just make sure your dh goes back for ALL the follow up counts, there's like 2 or 3, more if anything is found. Dh's was zero for all of them and we're 2.5 yrs out from the procedure, no surprises but we never had an easy time getting pregnant anyway so no promises here.
